Abstract: REFINING AGENT OF MOLTEN METAL AND           METHODS FOR PRODUCING THE SAME                 ABSTRACT OF THE DISCLOSURE           The present invention relates to a refining agent used for deoxidation, desulfurization, and dephosphorization of molten steel by a ladle refining, as well as methods for producing such a refining agent.  The general practice in ladle refining is to use for the refining agent both so--called flux, which is mainly composed of CaO, and a Ca-based metallic additive.           In conventional practice, the flux and the Ca-based metallic additive are added to the molten steel separately.           It is an object of the present invention to provide a refining agent, wherein the flux and metallic CaO component act highly effectively on the molten metal.           A refining agent for metal according to the present invention essentially consists of:  a Ca Alloy, which essentially consists of Ca and at least one element selected from the group consisting of Al and Si, and a flux mainly composed of CaO and Al2O3, the Ca-alloy phases and the flux phases being integrally bonded to one another.           According to the method of present invention, the reduction of CaO by the metallic reducing agent allows the Ca alloy phase and flux phase to be very uniformly mixed with one another, with the result that the vaporization loss of metallic Ca can be suppressed to a high extent.

Abstract: ABSTRACT OF THE DISCLOSURE        The steering control system of the present invention includes a steering gear box mounted on an axle of a vehicle substantially of the midpoint between steerable wheels journaled on and connected to knuckle joints on the ends of the axle.  The input shaft of the gear box is connected to the steering wheel shaft by a slip joint.  The longitudinal axis of the input shaft, slip joint shaft and wheel shaft are all angled up-wardly and rearwardly with the total rearward angle being about 22° and the rearward angle of the input shaft being about 7°.  Mounting the gear box on the axle rather than on a sprung portion of the vehicle minimizes impact forces due to rough roads from being transmitted to the operator through the steering wheel and from damaging the gear box.

Abstract: ABSTRACT OF THE DISCLOSURE         A magnetotherapeutic plug enables the treatment of rectal and vaginal inflammations, especially treatment of hemorrhoids by direct action on inflamed tissue as well as treat-ment in cases of mucus discharge or pruritus ani, and comprises permanent multiple magnetized magnetic core.  The plug is adapted to the anatomic shape of rectal and vaginal cavities, so that it provides a reliable contact with the tissue, without sharp edges that could damage the tissue during use, so that it is applied easily and simply and stays in place without falling out during the treatment.  The magnetic field of the plug is constant, and the poles configuration is in the shape of rings, longitudinal bands, or other geometrical figures.  The magnetic flux density does not exceed 80 mT, preferably being from 20 mT to 40 mT.  The application procedure comprises a ten-days treatment, 1 to 4 hours daily.  The procedure wherein the plugs with different magnetic poles configuration are used alternately, e.g., ring-shaped first and then the shape of longitudinal bands or in some other combination, is the most convenient.

Abstract: Abstract A Mechanical heart system for implantation into the human body includes a pump (10) and control circuit (30). The pump (10) is run at a frequency which is a harmonic multiple of a normal heart beat frequency, and the pump chamber volume is reduced, proportionately to the increased pumping frequency.  The circuit (30) for controlling the frequency includes a phase locked loop (35) for implementing a predictive algorithm which adjusts the frequency dynamically based on heart muscle nerve ending signals, so as to synchronize the circuit output to the biologically determined heart beat.  The reduced displacement permits use of a smaller compliance chamber. A novel interconnection between the motor chambers (12, 12') of a plurality of such pumps (11, 13) eliminates the need for venting and compliance chambers (37) in a totally implanted heart system.

Abstract: ABSTRACT         The device that is used to blend liquid narcotic agents in the respiratory gas that is supplied to a patient makes it possible to use a closed respiration system to which an adequate quantity of narcotic agent, highly concentrated, is to be supplied in a small volume of respiratory gas, and also permits its use in an open system, in which larger quantities of narcotic agent are required.  Several reservoirs containing different narcotic agents are connected through a first switch and pump to a second switch.          The first switch can be operated to select a particular narcotic from the different reservoirs and the second switch can be oper-ated to pass the narcotic agent either to a vaporizer or a vortex chamber as desired.  The narcotic agent is vaporized in the nar-cotic agent vaporizer and then supplied, highly concentrated, to the patient in the respiratory air, which can be done here in a closed system.  Within the vortex chamber the narcotic agent is vaporized in the fresh gas flow that is then supplied to the patient as respiratory gas. A monitoring system monitors and controls the selected sequence with the data that is supplied from the corresponding metering systems.
